Description
Verfahren zur Herstellung eines aktiven Sauerstoff enthaltenden Waschmittels. Gegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung eines beständigen, aktiven Sauerstoff abgebenden Waschmittels, das dadurch gekennzeichnet ist, dass man das Natriumsalz des durch Einwirkung von weniger als der molekularen Menge Pyrophosphorsäure auf Stearinalkohol er hältlichen Stearinalkoholpyrophosphorsäure- esters mit Wasserstoffsuperoxyd behandelt.
Beispiel: <B>290</B> kg Stearinalkohol werden mit 90 kg reiner Pyrophosphorsäure bei 100 bis 110 verestert.
Darauf wird das Reaktionsgemisch mit 40 kg Atznatron neutralisiert und durch Umkristallisieren aus Alkohol und Äther der reine Natriumpyrophosphorsäureester von folgender Formel erhalten: R2Na=P207 wobei "R" den Alkoholrest darstellt. 664 kg von dem so hergestellten Alkoholpyrophos- phorsäureester werden mit 215 1 Wasserstoff superoxyd 40%ig angeteigt und unter Zu gabe von wenig Alkohol bei 40 in Lösung gebracht.
Hierbei bildet sich analog dem Persalz des Natriumpyrophosphates ein An lagerungsprodukt in Form einer weissen Paste, in welchem 21/2 Mol Wasserstoff superoxyd auf 1 Mol des Alkoholnatrium- pyrophosphates kommt. Um zu einem trocke nen Produkt zu gelangen, ist es zweckmässig, den Alkohol vorsichtig im Vakuum abzu dampfen und den Rückstand in Äther auf zunehmen. Dabei fällt das Anlagerungspro- dukt als weisses körniges, kristallines Salz aus, welches abfiltriert und mit Äther nach gewaschen werden kann.
Das erhaltene Pro dukt besitzt einen ungefähren Gehalt von 62 % Fett und 5 % aktivem Sauerstoff und ist leichter wasserlöslich als der Fettalkohol- pyrophosphorsäureester und bildet sowohl als Paste als auch als Pulver mit Wasser stark schäumende Lösungen.
Das Produkt kann ausser für die allge meinen Zwecke vor allem auch bei der Textilveredlung zum oxydativen Nachseifen, zum Vorbleichen von Farbware, zum Beu- chen und Nachbleichen von Baumwolle, zum Erstbasten von Rohseide, zum Aufschliessen von Stärke und ähnlichen Zwecken nutz bringend Verwendung finden, zum Beispiel in der Haushaltwäsche.
Process for the preparation of a detergent containing active oxygen. The subject of the present patent is a process for the production of a stable, active oxygen-releasing detergent, which is characterized in that the sodium salt of the stearic alcohol pyrophosphoric acid ester obtainable by the action of less than the molecular amount of pyrophosphoric acid on stearic alcohol is treated with hydrogen peroxide.
Example: <B> 290 </B> kg of stearic alcohol are esterified with 90 kg of pure pyrophosphoric acid at 100 to 110.
The reaction mixture is then neutralized with 40 kg of caustic soda and the pure sodium pyrophosphoric acid ester of the following formula is obtained by recrystallization from alcohol and ether: R2Na = P207 where "R" represents the alcohol residue. 664 kg of the alcohol pyrophosphoric acid ester prepared in this way are made into a paste with 215 liters of 40% hydrogen superoxide and dissolved at 40% with the addition of a little alcohol.
Here, analogous to the persalt of sodium pyrophosphate, an addition product is formed in the form of a white paste, in which 21/2 mol of hydrogen superoxide is added to 1 mol of alcohol sodium pyrophosphate. In order to obtain a dry product, it is advisable to carefully evaporate the alcohol in vacuo and to absorb the residue in ether. The adduct precipitates out as a white, granular, crystalline salt, which can be filtered off and washed with ether.
The product obtained has an approximate content of 62% fat and 5% active oxygen and is more soluble in water than the fatty alcohol pyrophosphoric acid ester and forms strongly foaming solutions with water both as a paste and as a powder.
In addition to general purposes, the product can also be used in textile finishing for oxidative re-soaping, pre-bleaching of colored goods, loading and re-bleaching of cotton, first basting of raw silk, opening up starch and similar purposes. for example in household linen.
